Complete guide — how to use ChatGPT, fix common errors, manage billing, and get the most out of every feature.
If your ChatGPT 2FA code is not working, the most common cause is a device clock that is more than 30 seconds out of sync — TOTP authenticator codes are time-based and invalid if your device time is wrong. Enable automatic time sync on your device and regenerate the code. If that fails, use one of your backup codes to log in and then re-enable 2FA.
If ChatGPT shows 'access denied' or your account appears blocked, first check whether the issue is tied to one browser, one network, or your whole account. Then refresh the session, disable VPN/proxy and extensions, confirm you are in the correct account/workspace, and check whether the block is temporary or policy-related before contacting support.
ChatGPT temporarily restricts accounts after approximately 5–10 failed login attempts within a short period as a brute-force protection measure — the automatic cooldown typically lasts 15–30 minutes. Stop all login attempts immediately, wait at least 30 minutes, then try once from an incognito window on a clean network without a VPN.
If ChatGPT flags suspicious activity or temporarily restricts access, stop repeated retries first. Then sign out, use a clean browser session, disable VPN/proxy and request-modifying extensions, and retry from a stable network. If the warning appears across multiple clean environments, collect the exact message and escalate instead of forcing more attempts.
If your ChatGPT billing history is missing, first confirm you’re in the correct account/workspace and the Subscription/Manage page. Then compare ChatGPT’s billing view with your bank record (pending vs posted). If a posted charge exists but billing history/invoices don’t appear after ~24 hours, collect timestamp/amount/screenshots and contact support.
Most ChatGPT billing failures are caused by banks blocking international or recurring charges; update your payment method at chat.openai.com → Settings → My Plan, retry with a different card, and log out then back in to refresh your subscription status. If charged but not activated, wait 5 minutes and contact OpenAI support with your receipt.
ChatGPT Plus costs $20/month and payment fails in roughly 80% of cases due to bank-side blocks on international or recurring card-not-present charges — not a problem with OpenAI's system. Retry once from an incognito window with no VPN, then call your bank to authorize recurring charges from OpenAI. If you were charged but Plus did not activate, wait 5–15 minutes, sign out and back in, then contact support at help.openai.com with the charge timestamp, amount, and last 4 digits of your card.
To upgrade ChatGPT to Plus ($20/month), go to chat.openai.com → Settings → Upgrade plan; to downgrade or cancel, go to Settings → Subscription → Manage → Cancel plan. You keep full access through the end of your current billing period when downgrading — your chat history is never deleted regardless of plan.

ChatGPT shows a blank or white screen most often because a browser extension is blocking a required script, or because stale site data is cached. Open an incognito window first — if ChatGPT loads there, disable extensions one by one and clear site data for chat.openai.com to fix it in your normal browser.
To cancel ChatGPT Plus auto-renewal, go to chat.openai.com → Settings → Subscription → Manage → Cancel plan and confirm the cancellation. Your $20/month renewal will stop, but you keep Plus access until the end of the current billing period. Take a screenshot of the cancellation confirmation page as proof — the plan status should change to show an end date.
ChatGPT image generation requires a Plus, Team, or Pro plan — free users do not have access to DALL-E image generation as of 2026. If you have Plus and image generation still fails, confirm you are using GPT-4o (not GPT-4o mini) and check that the feature has not been temporarily disabled in your region via status.openai.com.
A ChatGPT CAPTCHA loop — where the CAPTCHA reloads immediately after you solve it — is almost always caused by a VPN IP flagged as a data center address or automation-like browser behavior. Disable your VPN, switch to a clean browser profile with no extensions, and stop rapid retries; this resolves the majority of CAPTCHA loops within 2 minutes.
When your card is declined by the issuer for ChatGPT Plus ($20/month), call your bank and ask them to authorize recurring online charges from OpenAI — this resolves the majority of issuer-side declines within minutes. Then retry once in an incognito window without VPN. If the card continues to fail, try a Visa or Mastercard credit card from a different bank.
To update your ChatGPT payment method, go to chat.openai.com → Settings → Subscription → Manage → Update payment method, then enter new card details and save. Note that ChatGPT does not allow you to change the billing email directly — billing is tied to your account's login email, which can only be changed through your account settings if your account is not linked to Google or Apple.
To downgrade ChatGPT from Plus ($20/month) to free, go to Settings → Subscription → Manage → Cancel plan and confirm — you keep Plus access until your billing period ends, then revert to free. To upgrade from free to Plus, click Upgrade plan on the same page and enter payment details. Plan changes take effect at the next billing cycle unless you are upgrading, which charges immediately.
ChatGPT 'conversation not found' usually means the chat link is broken, you are signed into the wrong account, or the conversation was deleted — not that the data is lost. Refreshing while logged into the correct account recovers most missing conversations within 30 seconds, as history syncs server-side.
Custom Instructions let you tell ChatGPT facts about yourself and how you want it to respond — once, permanently, across all future conversations. Go to Settings → Personalization → Custom Instructions, fill in the two text boxes, and save. ChatGPT applies these to every new chat automatically. No need to re-explain your role, tone preferences, or formatting expectations in every session.
ChatGPT Plus allows approximately 160 GPT-4o messages per 3-hour rolling window before automatically downgrading you to GPT-4o mini. Free users get roughly 10–15 GPT-4o messages per 3-hour window. The cap resets on a rolling basis — not at midnight — meaning if you sent your first message at 2 PM and hit the limit, you regain access around 5 PM, not at midnight. Switch to GPT-4o mini immediately to keep working while you wait.
If you hit a daily cap, wait for reset, reduce heavy requests, and use smaller prompts. Check whether your plan has different limits.
If you see duplicate ChatGPT charges, stop retrying payments immediately to prevent additional charges. Check your bank to distinguish pending authorization holds (which release in 3–7 business days) from posted charges (which are real billing events). If two posted charges of $20 appear for the same subscription period, contact OpenAI support at help.openai.com with timestamps and screenshots.
ChatGPT email verification links expire within 10–15 minutes — if your link says 'expired' or doesn't work, request a new verification email immediately and use only the latest link. If the link redirects you back to the login page instead of verifying, open it in an incognito window and clear cookies for chat.openai.com and openai.com before retrying.
Refresh the page, reduce request size, try another browser/network, and disable extensions. If the issue persists, check the status page and retry later.
A ChatGPT 403 error means access was forbidden — the most common causes are expired session tokens, browser extensions blocking requests, or VPN/proxy IP mismatches. Fix it by refreshing the page, clearing cookies for chat.openai.com, and retrying in incognito mode; if the error appears on long prompts, split them into smaller parts under 2,000 words.
Refresh the page, reduce request size, try another browser/network, and disable extensions. If the issue persists, check the status page and retry later.
When ChatGPT shows 'error in message stream', first retry once with a shorter prompt in an incognito window on a stable network. If it still fails, test another network/device, remove uploads/tools, and check whether the issue reproduces across accounts. If it fails everywhere, treat it as a platform-side incident and wait before escalating with timestamps and screenshots.
The 'Error in message stream' in ChatGPT means the real-time streaming connection that delivers words to your screen was interrupted mid-response — not that your message was lost. This error appears in roughly 60–70% of cases due to an unstable network connection or a VPN endpoint throttling the persistent connection; switching to a hotspot and disabling VPN resolves it for most users.

If ChatGPT is stuck loading history or projects, first check whether the issue is account-wide or only happening in one browser. Then refresh the session, test incognito or another device, and rule out extensions, VPN, or service incidents. If history fails everywhere, collect the exact error state before contacting support.

To report a ChatGPT bug effectively, include the exact error text, a timestamp, your OS and browser/app version, and clear steps to reproduce — reports missing even one of these 4 elements are resolved 2–3x slower by support. Start with a clean session (sign out, clear cache/cookies, disable extensions) to confirm the bug is reproducible, then submit via help.openai.com.
ChatGPT is available in over 160 countries, but specific features — including Advanced Voice Mode, DALL-E image generation, and some GPT Store capabilities — roll out region by region and may not be available everywhere simultaneously. Check openai.com/policies/usage-policies for the current list of restricted countries and features before assuming the issue is account-specific.
ChatGPT file uploads are limited to 512 MB per file and a maximum of 10 files per conversation — exceeding either limit causes an immediate upload failure. For files within the size limit that still fail, switching to a phone hotspot and disabling VPN resolves most network-related upload failures within 2 minutes.
GPTs are customized versions of ChatGPT built for specific tasks — a coding assistant, a writing coach, a customer support bot. Find them in the GPT Store at chat.openai.com/gpts. Click any GPT to open it and start chatting. Creating your own GPT requires a ChatGPT Plus account; using public GPTs is available on the free plan. No code required to build one.
To use ChatGPT, go to chat.openai.com, create a free account with your email or Google, and start typing a message in the chat box. ChatGPT responds immediately. Free accounts use GPT-4o mini; upgrading to Plus unlocks GPT-4o with higher message limits. No setup required — just describe what you need in plain language.
To update the name or company details on ChatGPT Plus invoices, go to chat.openai.com → Settings → Subscription → Manage → Billing details and update your name and company before the next billing cycle — changes apply to future invoices only. For corrections to already-issued invoices, contact OpenAI support at help.openai.com within 30 days of the invoice date.
To download a ChatGPT invoice/receipt, open Settings → Subscription → Manage and look for billing history/invoices. If invoices are missing, confirm you’re in the correct account/workspace, refresh in an incognito window, and compare with your bank charge status. If a posted charge exists but no invoice appears after 24 hours, contact support with timestamp and amount.
When ChatGPT blocks you due to limits: pause retries, check your plan/usage window, reduce concurrency, and avoid automation spikes. If limits are plan-based, wait for reset or upgrade.
ChatGPT temporary restrictions typically last 1–24 hours and are triggered by behaviors that look automated: rapid retries, frequent IP changes, VPN switching, or many failed logins within a short window. Stop retrying immediately, clear your session, disable VPN, and wait at least 30 minutes before attempting a clean sign-in from a stable network.

If ChatGPT looks blocked by regional restrictions, first confirm it’s not a browser/session/workspace issue by testing incognito + a second network (hotspot). Then disable VPN/proxy and retry. If the same restriction appears across multiple devices and networks, collect the exact message and escalate—don’t keep retrying.

If ChatGPT's desktop app won't let you log in, sign out and clear the app's cached credentials, then reinstall the latest version — the app stores session tokens locally, and a corrupted token file is the most common cause of desktop login failures. If reinstalling doesn't help, check whether the same account works at chat.openai.com in a browser.
If ChatGPT login fails on your iPhone or Android, force-close the app and reopen it, then clear the app's cache (Android: Settings → Apps → ChatGPT → Clear Cache; iOS: offload and reinstall). If that doesn't work, check your mobile data or Wi-Fi connection — mobile network restrictions and VPN apps are the second most common cause of mobile login failures.
Try incognito mode, clear cookies for the service, disable extensions, and retry. If you use Google/Apple login, re-authorize the provider and check for outages.
ChatGPT login errors affect roughly 3 methods: email/password, Google OAuth, and Microsoft OAuth — all routed through auth0.openai.com. The fastest fix is to delete all openai.com and auth0.openai.com cookies, then retry in a fresh browser window. If you see a redirect loop, corrupted session cookies are the cause in over 80% of cases. If you see 'email or password incorrect' but your credentials are right, you likely signed up via Google or Microsoft and have no direct password — use the SSO button instead.
A ChatGPT login loop — where you enter credentials, get redirected back to the login page, and repeat indefinitely — is almost always caused by corrupted cookies from openai.com or auth0.com. Clear site data for both domains in your browser, then retry; this resolves the loop in over 90% of cases within 60 seconds.
If ChatGPT keeps sending you back to the sign-in page, the fastest fix is to try an incognito window. If that works, clear ChatGPT/OpenAI cookies in your main browser — including auth0.com, which is the authentication provider OpenAI uses — disable extensions, and retry on a normal network (no VPN/proxy). If it fails on multiple devices and networks, it's more likely account/SSO or a platform-side login issue.
Try incognito mode, clear cookies for the service, disable extensions, and retry. If you use Google/Apple login, re-authorize the provider and check for outages.
If ChatGPT's login screen is stuck on loading, a JavaScript-blocking extension or cached session token is almost always the cause — open an incognito window and clear cookies for chat.openai.com and auth0.com in your main browser to fix it in under 2 minutes. On mobile, force-close the app and toggle Airplane Mode on then off to reset the connection.
If ChatGPT login is not working, the fastest fix is to open an incognito window and clear cookies for chat.openai.com and openai.com in your main browser — this resolves over 80% of login failures caused by stale session tokens. If that fails, reset your password and check status.openai.com for ongoing outages.
Fix ChatGPT login problems by clearing site cookies, disabling extensions/VPN, completing OAuth re‑authorization (Google/Apple), and trying a different network. If you’re stuck in a loop, reset the session and verify you’re using the same login method as the account.
If 'Sign in with Apple' fails on ChatGPT, the most common cause is an Apple ID session conflict — sign out of your Apple ID on the device, then sign back in and retry. If you previously chose 'Hide My Email' when linking Apple to ChatGPT, you must use that same hidden email address going forward; ChatGPT cannot recognize your real Apple email in this case.
If 'Sign in with Google' fails on ChatGPT, start by opening an incognito window — this isolates whether the issue is browser extensions or cookies blocking Google's OAuth redirect to auth0.com. If incognito works, clear cookies for openai.com, auth0.com, and google.com in your main browser, then disable any privacy extensions that may block cross-site requests.

ChatGPT Memory lets the AI remember facts about you across conversations — your job, preferences, ongoing projects — without you repeating yourself every time. Enable it at Settings → Personalization → Memory. You can view, edit, or delete individual memories at any time. Memory is separate from conversation history and works across all devices on the same account.
ChatGPT conversation history is disabled by default in Temporary Chat mode and can also stop saving if Chat History is turned off in Settings — check Settings → Data Controls → Improve the model for everyone to confirm history is enabled. If history was on and messages are still missing, they are usually recoverable by refreshing on the same account and browser.
ChatGPT 'failed to fetch' errors mean the connection between your device and OpenAI's servers was interrupted — not that ChatGPT is down. The fix resolves in under 5 minutes for 80% of users by switching networks or opening an incognito window, since VPN interference and browser extensions cause the majority of these errors.
A ChatGPT network error means the connection between your browser and OpenAI's servers was interrupted. The most common causes are unstable internet, VPN interference, browser extension conflicts, or OpenAI server issues. Fix it by refreshing, switching networks, disabling VPN, or trying incognito mode. If the error only appears on long responses, enable the regenerate option and break your prompt into shorter parts.
A blank ChatGPT page after login is almost always caused by a broken session token or a browser extension blocking the page from rendering — opening an incognito window fixes it in under 2 minutes for most users. If incognito also shows a blank page, clear all cookies and site data for openai.com, then sign in again.
ChatGPT password reset emails are sent from noreply@tm.openai.com within 1–2 minutes — if yours hasn't arrived after 5 minutes, check your spam and promotions folders first, then confirm you're using the exact email address registered to your account. If you requested multiple resets, only the most recent link is valid; earlier links expire immediately when a new one is requested.
ChatGPT Plus costs $20/month and payment declines are most commonly caused by bank blocks on international or recurring online charges — call your bank to authorize the transaction, then retry once in an incognito window without VPN. If you were charged but Plus did not activate, sign out and back in and wait 15–30 minutes before contacting support.
Update your payment method, confirm your card supports international/recurring charges, and check your bank for blocked transactions. If charged but not activated, wait a few minutes and contact support.

Update your payment method, confirm your card supports international/recurring charges, and check your bank for blocked transactions. If charged but not activated, wait a few minutes and contact support.
The charge is almost always a temporary authorization hold that releases automatically within 3–7 business days — it is not a completed payment. Check Settings → Subscription to see if your plan is active; if the charge shows as pending in your bank, wait for it to clear before taking any action. If the charge is fully posted but your subscription is still inactive after 30 minutes, contact OpenAI support at help.openai.com.
Start with a clean session (sign out, clear cache/cookies, disable extensions), then verify plan/permissions, check status/incidents, and retry on another network. If it persists, capture logs/error details and contact support.
Update your payment method, confirm your card supports international/recurring charges, and check your bank for blocked transactions. If charged but not activated, wait a few minutes and contact support.
ChatGPT Plus is not available in all countries — if your region is unsupported, the subscription page will either not load or show an error. For supported countries, card declines due to country restrictions are usually fixed by calling your bank to authorize international recurring charges from OpenAI, or by using Apple Pay or Google Pay which bypass many regional card restrictions.
If your ChatGPT payment is pending or stuck processing, stop retrying. Check whether the charge is pending vs posted in your bank, then refresh the subscription page after signing out/in. If the payment posted but your plan didn’t update after 15–30 minutes, collect the timestamp/amount/last4 and contact support.
If you paid for ChatGPT Plus on one account but are using a different account, the fix requires signing into the specific account that holds the subscription — OpenAI cannot transfer a subscription between accounts. Check your payment confirmation email to find the billed email address, then sign into that account to access Plus features.
ChatGPT Plus ($20/month) in 2026 gives approximately 160 GPT-5.5 messages per 3-hour rolling window. GPT-4o was retired from ChatGPT in February 2026 and replaced by GPT-5.5 as the default model. o1 is limited to roughly 50 messages per week, o3-mini to 50 per day. When you hit the cap, ChatGPT falls back to a lighter model automatically.
If you were charged for ChatGPT Plus but Plus didn’t activate, wait 5–15 minutes, refresh the subscription page after signing out/in, and confirm you’re on the same account that made the purchase. If the charge is posted and access still doesn’t activate after 30 minutes, contact support with the charge timestamp, amount, and screenshots.
If you were charged $20 for ChatGPT Plus but it is not showing as active, sign out of all devices, wait 15–30 minutes for subscription provisioning, then sign back in and check Settings → Subscription. The most common causes are session cache, wrong account, or App Store vs web subscription mismatch — if Plus still does not appear after 30 minutes with a posted charge, contact OpenAI support.
A failed ChatGPT Plus renewal is almost always caused by an expired card, a bank block on recurring charges, or a billing address mismatch. Update your payment method immediately at chat.openai.com Settings → Billing, then manually retry the charge. You have a short grace period before losing Plus access, so act quickly.
ChatGPT promo codes fail most often because they are expired, region-restricted, or tied to a specific account type (new subscribers only, student email required, etc.). Verify eligibility in the code's terms, make sure you are applying it to the correct account in an incognito window without VPN, and check that you are not already a Plus subscriber — most promo codes are for new subscriptions only.
Wait for the limit to reset, reduce request frequency, and avoid rapid retries. If you hit a hard cap, upgrade your plan or use a backup workflow until the window resets.

Start with a clean session (sign out, clear cache/cookies, disable extensions), then verify plan/permissions, check status/incidents, and retry on another network. If it persists, capture logs/error details and contact support.
ChatGPT Plus receipt emails are sent from no-reply@openai.com or billing@openai.com within minutes of a successful charge. If you did not receive one, check your spam and promotions folders, confirm the payment was actually posted (not just a pending hold), and verify you are checking the email associated with your ChatGPT account. You can also download invoices directly from Settings → Subscription → Manage without needing the email.
ChatGPT Plus refunds are most commonly denied because the subscription was heavily used during the billing period, the request was made more than 7–14 days after the charge, or the subscription was purchased through the App Store (which uses Apple's refund policy, not OpenAI's). If denied, you can escalate by replying to the support thread with additional context — do not open a new ticket.
Update your payment method, confirm your card supports international/recurring charges, and check your bank for blocked transactions. If charged but not activated, wait a few minutes and contact support.
ChatGPT refunds typically take 5–10 business days to appear on your card after OpenAI approves the request. If your refund request is pending, check for a confirmation email from OpenAI — if you received one, the refund is approved and processing; if you received no response after 5 business days, reply to your support ticket to request a status update.
OpenAI processes refund requests within 5–10 business days; submit your request at help.openai.com with your account email and charge details. Refunds are typically granted only within 7 days of charge and only if you have not heavily used the subscription. The refunded amount returns to your original payment method in 5–10 business days after approval.
ChatGPT's context window limit is approximately 128,000 tokens for GPT-4o — roughly 100,000 words of combined input and output. When you hit 'request too large,' your conversation history plus your new message exceeds this limit. The fix is to start a new conversation and paste only the relevant context, rather than continuing in a thread that has grown too long.
ChatGPT web search (Browse with Bing/ChatGPT Search) requires a Plus plan and is not available on the free tier as of 2026. If you are on Plus and search still fails, the most common causes are a disabled search tool in your model settings, a network filtering your connection to Bing's search API, or a temporary service incident affecting the search integration.
If ChatGPT keeps showing 'session expired' every few hours or days, the cause is almost always a browser or extension that automatically deletes cookies — session expiry should normally last 30+ days. Check for 'Cookie AutoDelete' or similar extensions, ensure third-party cookies from auth0.com are allowed, and avoid using private browsing mode as your default since it deletes sessions on every close.
Try incognito mode, clear cookies for the service, disable extensions, and retry. If you use Google/Apple login, re-authorize the provider and check for outages.

The 'Something went wrong' error in ChatGPT is a generic catch-all that appears for dozens of different underlying causes — session expiry, browser extension conflicts, network throttling, or temporary server issues. The fastest fix for 70% of cases is signing out, clearing cookies for openai.com, and signing back in from a private browser window.
The 'Something went wrong' error in ChatGPT is a generic catch-all that usually means a session problem, a corrupted browser cache, or a temporary server issue. Fix it by signing out and back in, clearing your cache, or trying a private browser window. If it appears on every conversation, your account session may be corrupted and needs a full reset.
If cancelling ChatGPT Plus doesn’t take effect, first confirm you cancelled on the correct account and subscription page. Then check whether the subscription is still in a pending renewal state, refresh the billing session, and avoid re-subscribing by accident. If auto-renew still shows enabled after 30 minutes, contact support with screenshots and timestamps.
ChatGPT Plus ($20/month) typically activates within 5–15 minutes of a successful payment. If it has not activated after 30 minutes, sign out of all devices, wait, then sign back in and check Settings → Subscription. If the charge is fully posted to your bank but Plus is still inactive after 1 hour, contact OpenAI support at help.openai.com with the charge timestamp and amount.
Log out and back in to refresh your session, check your subscription status in Settings, and verify that your payment was successfully processed. Activation may take a few minutes after payment.
Update your payment method, confirm your card supports international/recurring charges, and check your bank for blocked transactions. If charged but not activated, wait a few minutes and contact support.
ChatGPT Plus costs $20/month and OpenAI typically approves subscription refunds only within 7 days of the charge and only if the service was not heavily used. Submit your request at help.openai.com with your account email, charge date, and bank statement screenshot — approved refunds appear on your card within 5–10 business days.
A ChatGPT suspicious activity flag typically triggers a 24-hour cooldown period — stop all login attempts immediately, disable your VPN, and wait. The system flags activity when it detects logins from multiple geographic locations within a short timeframe, rapid failed login attempts, or access patterns that resemble automated tools. After 24 hours, log in once from your regular network without a VPN.
ChatGPT responses stop midway for two different reasons: the model hit its output token limit (roughly 4,000 tokens or about 3,000 words per response), or the streaming connection dropped mid-transfer. You can distinguish them by typing 'continue' — if ChatGPT continues seamlessly, it was a token limit; if you get a network error, it was a connection drop.
Wait for the limit to reset, reduce request frequency, and avoid rapid retries. If you hit a hard cap, upgrade your plan or use a backup workflow until the window resets.

If you can’t update your payment method for ChatGPT, try the billing page from Settings → Subscription in an incognito window with extensions/VPN off. If the update form fails, clear site data for chat.openai.com/openai.com and retry on a stable network. If it still fails across devices, collect the exact error and contact support.
ChatGPT allows up to 10 files per conversation and a maximum of 512 MB per file. If you hit the upload limit within a conversation, start a new conversation — file counts reset per conversation, not per day. Spamming retry attempts after hitting limits can trigger a temporary suspicious activity flag; wait and plan your uploads instead.
When ChatGPT blocks you due to limits: pause retries, check your plan/usage window, reduce concurrency, and avoid automation spikes. If limits are plan-based, wait for reset or upgrade.
ChatGPT Plus users get approximately 40–80 GPT-4o messages per 3-hour window before hitting rate limits; free users get a lower cap on GPT-4o mini. Usage limits reset on a rolling window, not at midnight — so if you hit a limit, you typically regain access within 1–3 hours rather than waiting until the next day.
To update VAT, Tax ID, or billing address on ChatGPT, go to Settings → Subscription → Manage → Billing information and update your details before the next billing cycle — changes apply to future invoices only. VAT is applied based on your billing address country; adding a valid VAT number for EU business accounts removes VAT from future charges. For corrections to past invoices, contact OpenAI support.
ChatGPT verification codes are delivered from noreply@tm.openai.com within 1–2 minutes — if you haven't received one after 5 minutes, check your spam folder first, then verify your email address for typos and request a new code. SMS codes can take up to 3 minutes; if they still don't arrive, confirm your phone number includes the correct country code.
ChatGPT voice input requires microphone permission granted at both the browser level and the OS level — if either is blocked, voice will fail silently or show a microphone error. Check browser permissions first (the padlock icon next to the URL shows mic status), then check OS-level microphone privacy settings, which on macOS and Windows can block permissions even when the browser appears to have them enabled.

If ChatGPT login is not working, first test incognito + a second network to separate browser issues from account issues. If incognito works, clear site data for chat.openai.com/openai.com and disable extensions. If it fails across devices and networks, check for account/workspace access blocks and platform incidents, then contact support with timestamps and screenshots.
